Define dispersion of light class 7
WebRefraction of Light is the phenomenon that involves the bending of light when it travels from medium to another.. In refraction of light, a change in velocity of the light and direction of propagation occurs. When light travels through a substance with a different refractive index, refraction of light takes place.. The cause behind the change in direction is the … WebJun 18, 2024 · When white light is passed through a glass prism it splits into its spectrum of colours (in order violet, indigo, blue, green, yellow, orange and red) and this process of white light splitting into its constituent colours is termed as … A rainbow is formed when sunlight passes through water droplets and disperses … Metamorphic Rocks, Characteristics of Metamorphic Rock , Foliated, Non …
